Abstract: Continuing improvements in observational technologies are providing a wealth of new observations of disk structures that surround B-emission (Be) stars. For example, high-resolution interferometry in the optical and the infrared now routinely provides information at sub-milliarcsecond scales advancing our understanding of the structure and the physical conditions in the circumstellar regions. However, reconstructing images directly from observational data is not possible since the (u,v) plane coverage is unfortunately still quite exiguous. There remain key unanswered questions such as what is the mechanism that launches the material off the star and why do some B-type stars form a disk and later lose it while other disk systems remain stable for decades? Detailed theoretical models tightly constrained by observations are required to make progress on these longstanding questions.
